Abstract
Heavy metal pollution is a major environmental stress affecting plant growth and development. The heavy metal cadmium inhibits various physiological processes in plants, including seed germination and seedling growth, photosynthesis, and antioxidation. Extensive research has been conducted on the toxic effects of Cd on plants and the mechanisms of Cd tolerance. Here, we review recent advancements in our understanding of the absorption, transport, and accumulation of Cd in plants and the mechanisms of Cd tolerance.
摘要
重金属污染是影响植物生长和发育的主要环境胁迫之一。重金属镉抑制了植物的各种生理过程，包括种子萌发和幼苗生长、光合作用和抗氧化作用。人们对 Cd 对植物的毒性作用和 Cd 耐受机制进行了广泛的研究。在这里，我们综述了近年来人们对植物吸收、转运和积累 Cd 以及 Cd 耐受机制的理解的进展。
